It's about a brother x sister relationship, the brother feels like he have to act as a father for his little sister, since their parents broke up, but he suddenly finds out that he's falling for her and attack her while she's sleeping, and that's why it's called Oyasumi Sex (Good Night Sex).
Different it's what i can say about this one
You know that incest thing were they make it clear that the sister it's actually a step-sister? Well i don't remember hearing that in this hentai, so well... thats different. Another point is that it shows both perspectives, the brother (who thinks he is doing
something wrong), and the sister (who wants him to do it, but don't have the courage to say it).
It was good to watch but not too appealing, you might look for something else if you want more "action".
I started watching hentai 10 years ago. And I lost count of the hentai's I've watched till now. But this is my first Hentai review! Know what that means? This is by far my most favorite hentai of all times! But there is still 1 ep left to air when I'm writing this.
))Story: THIS IS INCEST! If it's not your thing, stay away! (mild spoiler ahead, equivalent to plot)
The story is about a young boy, who has to take care of the family, after his father's death. He raises his younger sister with much affection and love. He took her sister, always
being with him, for granted until one certain day: When his sister told him that she got a love confession from one of her classmates. But little did he know that she only lied in order to make him jealous! Thus their illicit relationship starts with much passion.
))Art: I really loved it. There was lot of detailing and everything had that smooth flow of animation!
))Sound: The music was very soothing and it felt like I was playing my favorite oldschool rpg. Sadly, it was very mild to give a lasting impression. But I bet you'll hum it all day, if u rewatch it paying attention to music particularly.
))Character: There is a explanation to the development they have, and everything makes sense. That's all you can expect from an hentai ova.
))Enjoyment: I nly wished I hadn't fapped so early into the episode. There was still so much I wanted to enjoy. Well I'm going to watch it only countless times again! I'll catch up..
))Overall: 10 for everythin, 'cause most of the hentai series these days suck on several levels. This is a gem among gems. It's similar to Virgin night, if you know how famous it was during it's times.
All right... What the fuck Japan...
I know Japan has some weird shit with "Imouto x Onii-chan" relationships, but this hentai is next level fucked up. There is absolutly no way for me to write this review without spoilers, and there seems to be no synopsis for it so Im going to right a small one of my own, so if you want to jump into this hentai without knowing shit you might want to skip what Im about to say. Be warned!
The story is borderline fucking ridiculous. So apparently the older brother has a "thing" for his little sister, so therefore, every night when she
sleeps he decides to go ahead and do some lewd shit to her without waking her up. ( ͡° ͜ʖ ͡°) It turns out that the little sister, also has a "thing" for his brother, and she is aware of what happens every night, yet she decides to go along with it and pretends to be asleep because she enjoys it. Thats pretty much the gist of it, so if you find that appealing you may as well enjoy it. (Fucking Weeb)
The Art and Sound to be fair is pretty damn good for a hentai. Pretty cute art style and dope loli pleasure and breathing noises ( ͡° ͜ʖ ͡°).
Overall, this aint the fapping material for me so Im giving it a solid 4/10. <3
The story is about a boy who takes care of his younger sister after the death of his father. Their sibling relationship worked well until his sister told him there is someone to whom she felts love. For that, the boy becomes jealous and from next night he regularly starts rape his sister with presumption that she sleeps and doesn't realize it. Brother and sister's sexual life just begun.
First thing you should know is that I don't like anime titles with same or similar story. If it's just a side storyline and it's processed well, I don't have a problem with it, but when it
is a main plot story, it is processed very poorly, the viewer doesn't feel any emotion and also it is a hentai, it cannot be good (perhaps just for sexual satisfaction) - and this is exactly the problem of this anime. Also, the characters are written badly, dialogues are bad and at all, the content of this piece is terrible, at best. It just can't be enjoyable for me.
Maybe it doesn't look like that, but this is one of the best hentai anime I've seen. Unlike them, technically it isn't bad and I could watch it more or less without problems. In addition, I liked the soundtrack, which I consider the best positive of this anime.
Finally, I give it one point out of ten, while it could be better (but unfortunately is not).
